Abstract

AES key expansion algorithm doesn’t have one-way property, and it can’t prevent the sub secret key reverse. So an improved algorithm of AES key expansion based on Iterative-Compression was proposed in this study. The algorithm confused initial key by cyclically shifting, and then the 128-bit key iteration obfuscated compressed into a 32-bit secret key. The first sub key was generated by the key word, and the follow sub keys were extended through recursive computation according to the first sub key. In the end, results of the one-way property analysis and FPGA simulation demonstrate that the one-way property strength of the improved key expansion algorithm is 296. And it meets high efficiency requirement.
